Hallo and greetings to template developer great job, i love it!

Just a stupid silly question, shurely been asked already many tines:
How can I avoid problems with internet explorer ?
I mean, I noticed, that my customized template shows wrong on IE, In particular the top heather grey row, where categories pull down is, shows all on the right side , outside the page....

Is this onlu my problem?
Is there a simple solution??
